Abstract (en)
[origin: US2020343508A1] A short circuit current interruption method of a battery system including: stacking a plurality of prismatic battery cells and connecting the plurality of prismatic battery cells with a parallel connection bus bar in parallel to form a battery block, wherein a sealing plate of the prismatic battery cell is a plate material having flexibility that deforms when an internal pressure rises due to an internal short circuit, and when a rise in the internal pressure due to the internal short circuit of the prismatic battery cell causes deformation, the deformation of the sealing plate is detected, and when an amount of deformation exceeds a setting value, the short circuit current of the battery connected in parallel with the internally short circuited battery is interrupted.
